Carbon steel structural beams are manufactured in two configurations. Both are constructed with a vertical web in the center of the beam, with horizontal flanges on top and bottom. The structure of the beam provides superior load-bearing support.
Standard American Beams – Also known as Junior Beams, S Beam, or I Beams have tapered flanges for increased strength of the flanges. Wide Flange Steel Beams – Also known as W Beams or H Beams have non-tapered flanges that are wider than the standard S or I beams.
